December 2026 social media calendar for small businesses
December 2026 is packed for small businesses. Hanukkah starts at sundown on Friday, December 4 and runs through December 12. Christmas Day, a federal holiday, falls on Friday, December 25. Plan holiday hours, gift posts and preorder deadlines in November so the busiest weeks of the year don't catch you posting late.
Updated
December is the month most small businesses overpost and underplan. Plenty of shops throw up a holiday graphic on the 24th and call it done. The posts worth making are planned weeks earlier: gift guides, holiday hours, last order dates and a thank-you to your regulars.
Every date on this page has a source you can click. If we could not verify a day, we left it out.
Pick three or four dates that fit your business, not all of them. A bakery has every reason to post for Hanukkah and Christmas. A landscaper might skip both and post for World Soil Day on December 5. Each date lists the businesses it suits and sample post ideas, and the whole month comes as a CSV you can drop into your own planner.
